FTS now supply a full range of Septic Tanks from 2000 litres to 25,000 litres from manufacturers including Klargester, Harlequin and Clearwater 

A septic tank consists of a two or three chamber system that retains sewage from a property for sufficient time to allow the solids to form into sludge at the base of the tank, where it is partially broken down through anaerobic digestion. The remaining liquid in the tank then overflows from the tank by means of an outlet pipe to a drainage field.
